Title:
VEHICULAR BRAKE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018016268
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular brake control device capable of making accuracy in adjusting the pressure of a wheel cylinder pressure less likely to be lowered, when increasing the wheel cylinder pressure by driving a holding valve.SOLUTION: A control device 100 is a vehicular brake control device. The control device performs a pulse pressure increase control for alternately repeating a first period in which an instruction opening to holding valves 34a-34d is made greater than an opening target value and a second period in which the instruction opening is made smaller than the opening target value, and performs a linear pressure increase control for gradually increasing the instruction opening to the holding valves 34a-34d. Further, when operating a brake device 10 to increase a WC pressure, the control device 100, when a WC pressure detection value is at a selected determination value or more, starts performing the linear pressure increase control, and when the WC pressure detection value is less than the selected determination value, starts performing the pulse pressure increase control.SELECTED DRAWING: Figure 1
